전술 네트워크는 통신 인프라의 부족과, 산악 지형 등의 지형적 특성에 의하여 원활한 통신이 이루어지지 않는 경우가 생긴다. 무선 메쉬 네트워크 (WMN)는 메쉬 포인트들의 멀티-홉 통신을 통하여 별도의 통신 인프라 없이 넓은 지역에 대하여 무선 통신을 공급한다. 따라서, 전술 네트워크에서 무선 메쉬 네트워크의 활용 가능성은 매우 크다. 그러나 기존에 연구되었던 무선 메쉬 네트워크는 메쉬 네트워크를 구성하는 메쉬 포인트들의 이동성을 고려하지 않는다. 본 논문에서는 전술 상황을 고려하여 메쉬 포인트들이 그룹 이동성을 갖을 때 예상되는 MAC의 collision 문제와 PHY의 채널 사용 문제를 해결한다. Wireless mesh network (WMN) has recently emerged as a promising technology for tactical operation. If a platoon is organized with MPs, this system is suitable for tactical coverage is given for battle field where there is a shortage of wired infrastructure. However, MPs of typical WMN are generally fixed. This condition does not apply to diverse tactical scenarios. In this paper, it is considered that MPs have group mobility for flexible tactical networks. We propose cluster based multi-channel MAC scheme for mobilie WMN with single antenna condition. We have reduced the collision problems and message storming problems occur by mobility, so the reliability of WMN has been improved. Consequently, reliable communication is guaranteed by our framework in mobile WMN.

This article examines the early literature of Choi, Choon-Hae. The aim is to find the aesthetic characteristics inherent in his work. In addition, I will examine his literary thinking by confirming the imagination and literary transformation of ‘soil’. For this purpose, I should first examine the influence of the < 교단 아동문학 동인회; Teachers Group for Children’s Literary >, which he had worked on before his introduction on literature organization. I will also notice changes in literary trends such as < 동시의 시운동; Poetry revolution of Children’s Poetry > in the late 1960s. He faced reality, not ideological or fantastic concentricity. And we have dealt factually with the contemporary painful social phenomenon. He did not capitalize on ideology or embrace the critical realism. However, socio-cultural imagination has expressed the absurd worlds. He tried to find his anxieties and his identity with his soil. It is a way of criticizing painful life and absurd reality. This opportunity was provided a clue to discuss the future of his literature review more closely.

This paper was to find out the design methodology for korean railway station of steel structure using by wooden structure system. Traditionally Korean architecture was made by wooden structure system what is called Gong-Po (wooden bracket structure system). The abundant ornament of Korean architecture is resulted from the composition rule of Gong-Po(wooden bracket structure system). But Korean wooden structural system have a limit in constructing large building, for example railway station, airport terminal, convention center etc. It is needed to convert wooden structure system into steel structure system. But there are many differences between wooden structure and steel structure in texture, material strength, joint system of elements etc. In this paper, we will show you how to make a joint system for steel structure of railway station and how to present the traditionality of Korean architecture in railway station.

현재 각 역에서의 열차 출입문 취급(닫힘) 시간은 기관사가 감각적으로 판단하고 있다. 그러나 기관사마다 차이가 있어 열차의 정시성이 감소하고 차내 혼잡이 가중되고 있다. 또한, 출입문이 닫히는 중에 승객들의 무리한 승차로 열차 지연은 물론 승객 안전에도 큰 위험요인이 되고 있다. 본 논문에서는 기관사에게 출입문 취급시간 제공과 승강장 진입 및 대기승객에게 출입문 닫힘 예고시간을 심볼 및 숫자로 제공하여 정시성과 승객들의 안전을 확보 하고자 하였다. 제안된 시스템은 출입문 열림을 센서가 검지하면 해당 역의 정차시간을 타이머로 카운트하여 출입문 취급 시간과 닫힘 예고 시간을 표시기를 통하여 기관사와 승객에게 제공하도록 구성되어 있다. Currently, each of the trains at the station, locomotive engineer closes door at his own sensual time, which is different individually. These decrease punctuality of the train and aggravate vehicle congestion. Also, the boarding of passengers during the door closing cause the train delays and is a big risk factor to passenger safety. In this paper, we proposed door closing time notice system, which provide the driver with the door handling time, the passengers waiting at the platform or entering into the platform with the door closing time - by number and symbols - to improve the train punctuality and safety of passengers. The proposed system detects opening of the train door at the station using the sensor, counts to a specific time at each station and provide/notice to the locomotive engineer and passengers using the configured indicator.

Children’s literature of Daegu-Kyeongbuk area was continued of enlightenment and education from Japanese colonial era to activities after the liberation. Followed by 〈Joseon children association〉(1946. 4.), 〈The Society of Daegu children’s literature〉 was founded in late 1950s. This group has given some meanings to the local children’s parnassus. One of them was constantly looking for competent writer and welcome them as a new member. We can identify that they prioritized the goal of seeking for excellent writer and publishing a good anthology. As a result, they developed some meaningful movement such as overcoming the alienation, creation, and reversepositive of war parnassus. The following was that they issued an organ to present their works. This activity gets credit by obtaining specific subscribers as well as the desire of creation. Especially, writing education was one of the literature educating movement focused on teachers. Thus 〈The Society of Daegu children’s literature〉 breathed new life into the children’s creative activities for the children readers with expanded base of local children’s parnassus.

George de Planson was the Russian Consul-General in Seoul from 1906 to 1908 year. The name of the Korean Emperor was written on Plason`s patent. It means. that Russia has not recognized the right of Japan to a protectorate over Korea. Therefore, Japan could not accept such diplomatic action Russia. Japan used the occasion to resolve a question of Japanese right for protectorate over Korea. After the Russo-japanese war in 1904-1905 Portsmouth peace treaty was concluded between Russia and Japan. Russia believe that independence of Korea is not ignored by this treaty. And also believe the treaties, which signed in 1884 and 1888 years between Russia and Korea, still have the force. Therefore, by the insistence of russian government, the Russian Consul-General in Seoul would have to get his exequatur from the Foreign Office of korean government in Seoul. Japan could not accept that russian argument. Russo-japanese diplomatic war over Korea began. Especially, marquis Ito thought that Russia deliberately ignores the rights of Japan in Korea. And he did not want, that this case become a precedent for non-recognition of Japan`s right to protection on Korea. But this problem has been solved surprisingly. The new minister of foreign affairs of Russia, Izbolskii has pursued pro-English policy and on the extension of this policy he also pursued pro-Japan policy. He accepted all requests from Japan. So He agreed with issue of new patent for Planson and receipt of Plason`s exequatur from Japanese Government. However, the question of treaties between Korea and Russia had no resolution. Therefore, Japan had to sign another two new treaties with Russia in 1907 and 1910 year.

1930년대 초 계급주의 동시문학의 생태학

김종헌(Kim Jong-Heon) 한국아동문학학회 2013 한국아동문학연구 Vol.- No.24

이 연구는 1930년대 계급주의 동시의 문학생태학적 지형도를 살펴보는 것을 목적으로 한다. 1930년대 초 계급주의 동시문학은 카프의 영향 아래서 두 가지 담론에 의해서 계급의식을 확립해 간다. 먼저 근대담론의 호출에 응답한 타자성의 인정이 그것이다. 서구 근대의 개인적인 주체가 동시문학을 규정한 것이다. 이는 동요와 동시에서 집단적인 정서의 반영을 탈피하여 아동 개인의 정서의 반영을 요구하게 된다. 한편 이 시기 계급주의 동시문학을 추동한 또다른 담론은 계급성이다. 카프의 담론에 의해 분할되고 배제된 동시문학은 계급담론의 동일화 과정을 통해서 타자를 배제하고 억압하였다. 따라서 계급주의 아동문단은 타자 담론을 복제하여 자신의 담론으로 오인하면서까지 소년문예단체를 결성하고 동일화의 과정을 거치게 된다. 이는 당연히 천편일률적인 작품의 창작을 초래하는 문제를 지니게 된다. 이 과정에서 현실인식을 바탕으로 하는 계급의식과 현실의 실천적 상호관계를 둘러싼 소년문사 간의 갈등을 초래하게 된다. 이러한 일련의 과정 속에서 동요와 동시가 분화되었고 계급주의 동시문학의 계급의식이 형성되었다. 즉 집단적인 정서의 표현에서 개별 아동 정서의 표현을 거쳐 현실인식에 까지 나아가게 되었다. 이처럼 계급주의 동시는 선명한 주제를 부각시키는 것으로 당대 시인들을 호출하였다. 그리고 소년문사와 독자에게 계급의식을 계몽하는 방향으로 詩作활동이 이루어졌다. 그것은 계급주의 내부에서 상호 견제와 비판을 통해서 그 정체성을 뚜렷이 하였음을 알 수 있다. 물론 동시의 형식을 고민하였으나 그것은 예술의 차원이 아닌 어디까지나 현실인식을 반영하기 위한 억지스러움을 배격한 자연스런 율격정도에 지나지 않았다. 즉 동요의 예술적인 승화라기보다는 프로문학의 투쟁의식을 반영하는 과정에서 나타난 동시형식의 변화였다. This study aims to investigate the geography of socialistic in children’s verse in the early 1930s. In the early 1930s, children’s verse focusing on socialistic were developed to dispute surrounding empire-building and class capacity between younger writers and organizations within classes. Through this process, perfunctory differentiation was achieved from children’s verse based on song following the division of Changga(창가) and children’s song. This awareness of reality was developed from collective emotional expression through the expression of individual young children. On the basis of this, it focuses on a series of processes that express socialistic, child’s mind. With this, proletarian literature established more clearly the author’s values and identity of children’s poem literature that makes the struggle’s context more identifiable. This change in children’s verse appears in a process that reflects struggle consciousness rather than the artistic sublimation of children’s verse based on song.

이종기의 1950년대 초기동시 연구

Lee Jong-gee announced a juvenile poetry, 'Autumn(「가을」)' in a magazine 'Children's World' and he was an active poet in magazines 'Children's World(『소년세계』)' in 1950s and 'A New Friend(『새벗』)' in 1960s. As a budding poet, he published a juvenile poetry of free rhymes and his poem was beyond a form of nursery songs. And he gave a concrete shape to his juvenile poetry with the lyrical images while he thought of science and history as a means of recognition of realities. Likewise, he published some poems regarding the problems of human realities and strong lyrical characteristics. However, His discourses about juvenile poetry focused on the experimental epic juvenile poetry and they were concerned about a juvenile poetry of free rhymes and ‘The affection of the sky and the earth’(『하늘과 땅의 사랑』). Though he experienced the hard days of war and economic development, we could not find the any ideology and the conscious efforts for the children enlightenment in his poetry. In his poems, we could find disidentification for the recovering the conflict between the world and the self. Thus, we have to reconsider the emphasis on the experimental epic juvenile poetry and free rhymes in the controversy of discourse. From the early lyric poems to the late epic poems, Lee Jong-gee formed the way of poetic thinking very extensively but we cannot divide his juvenile poetry by stage. Because his reactions on his poetry was consistent in spite of a slight change in the subject and formation, the self was not united in the early lyrics -not in the harmony of a self and his world. These poetic reactions were shifted to the history and national consciousness by means of formational changes in his late long-length juvenile poetry and epic juvenile poetry. So we'd like to inspect closely how the subject of his lyrics reacts to realities in Lee Jong-gee's poetry.

The demand for renewable energy systems in buildings are increasing to save energy, to satisfy the renewable factor regulation, and to build a sustainable building. Each building has a distinct load profile and renewable energy resources, so the optimized portion of using renewable energy is each building is always different. To find the optimized renewable energy system, the engineer uses building energy simulation tools which are not good at comparing many systems, and hard to learn. In this study MORE-B(Model for Optimizing Renewable Energies in Buildings) is developed to analyze many renewable energy system cases on energy, renewable factor, net cost, and CO2.. To analyze many cases, the study suggests fast and efficient formulas and algorithm for MORE-B. Then it will be compared with EnergyPlus and HOMER for verify the corectness of MORE-B. Finally some examples of case studies done by MORE-B will be shown.
